The present invention relates to improvements in line composing and type casting machines of the general class disclosed in United States Letters iatent, No. 36,532, granted September 16,

. 1890, to O. Mergenthaler, and more especially to an attachment for quadding out and centering the matrix lines in machines in that general class, an embodiment of such an attachment being shown and described in my prior application,

1 Serial No. 562,398, filed September 11, 1931.

The primary object of the present invention is to provide a more simplified and improved quadding and centering attachment of such character whereby the construction and operation thereof are facilitated and the machine may be operated to make casts either from full matrix lines, whether or not they contain the usual expansible spacebands, or from short matrix lines whether or not they contain such spacebands, and which will be quadded out or centered re gardiess of the length of such lines, thus enabling machines of this class to meet most conveniently and effectively all conditions or requirements of service.

To these and other ends, the invention consists in certain improvements and the combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings,

The preferred embodiment of the invention is shown applied to a linecomposing and type casting machine of the class hereinbefore referred to, but it is to be understood that the invention is not restricted to the precise construction shown as equivalent constructions are con- Serial No. 574,003

templated and such will be included within the scope of the claims.

In the present instance, 1 represents the usual vise cap of a line composing and type casting machine of the class referred to, 2 and 3 represent respectively the left-hand and right-hand jaws of the vise as commonly used in such machines for clamping and locking the matrix line M5 between them and in front of a mold having a slot for the casting of a type bar or slug therein, the vise jaws being both movable in the vise cap 1 in directions toward and from one another, and 4 represents the usual sc-called first elevator which conveys the matrix lines into position between the vise jaws and in front of the mold prior to the making of a cast therefrom and removes the matrix line from such position after the cast has been made, in the manner usual in machines of this class.

The vise jaws 2 and 3 have toothed extensions or rack bars 5 and 6 secured thereto, and a gear pinion 7 is mounted to cooperate with these rack bars, it being mounted on a shaft 8 which is revolubly mounted in the vise cap 1 and provided at its forward end with a knob 9 by means of which it may be manipulated, and the shaft 8 with the pinion 7 thereon, is shiftable axially in the vise cap, either into a position where it will cooperate or engage the teeth of the rack bars 5 and 6 and thereby form a motion-transmitting connection between the jaws, or into a position forward of the rack bars where it will be out of engagement therewith. A spring-pressed plunger 10 is provided in the vise cap to engage in one or the other of a pair of axially spaced grooves 11 in the shaft 3 and thereby retain the pinion 7 yieldingly in either of the positions referred to.

The vise jaws are provided with closing mechanism which, in the present instance, is like that shown in my prior application hereinbefore referred to, it comprising an extension 12 on the jaw 3, a link 13 pivotally connected thereto at its lower end, the upper end of this link being pivotally connected to the lower end of a substantially horizontally swinging lever 14 which moves approximately in the direction of movement of the jaws, a block 15 being pivotally connected to the link 13 and lever 14, a rod 16 one end of which is freely movable longitudinally in the block 15 and the other end of which extends through a pin 17 and is provided with adjustable lock nuts 18 and 19 at opposite sides of said pin, a tension spring 20 encircling the rod 16 and being attached at one end to the block 15 and at its other end to a collar 21 suitably fixed on said rod.

The pin 17 is carried on a lever 22 which is pivoted on a shaft 23, and a second lever 24 is also pivoted on the shaft 23 and is provided with an ear or lug 25 arranged to bear against one side of the lever 22 and to move the latter lever in a direction to apply tension to the spring 20, the levers 22 and 24 being connected yieldingly by a tension spring 26 which acts in a direction tending to hold the lug 25 on the lever 24 against the lever 22. The lever 24 is provided with an arm 27 which is pivctally connected by a link 28 to a lever 29 which latter is movable vertically at appropriate times in the operation of the machine, as will be clear from my above noted prior application.

The operation of the jaw-closing means as above described is substantially the same as in my said prior application, it being deemed sufficient for the purposes of the present invention, to explain that after the first elevator 4 has descended to lower a matrix line into the space between the vise jaws, the lever 29 moves downwardly, thereby causing the levers 22 and 24 to swing toward the left in Fig. 1, thereby pulling the rod 16 in said direction and applying tension to the spring 20, thus causing the block 15 and link 13 and lever 14 to move toward the left in Fig. 1 or Fig. 4 and causing the jaw 3 to move toward the left or toward the left-hand jaw 2. While quadding out one end only of a line as, for example, occurs at the end of a paragraph, the pinion 7 will be pulled forwardly, thereby disengaging it from the rack bars 5 and 6, and the right-hand jaw 3 only will then be closed in against the matrix line and will close the end of the mold slot not closed by the matrix line, but if a matrix line is to be centered or indented equally at both ends, the pinion 7 will be set in its rear position in engagement with the rack bars 5 and 6, it then forming a motion-transmitting connection between the vise jaws so that movement of the jaw 3 toward the left will cause an equal movement of the jaw 2 toward the right, so that both jaws will then close in against the respective ends of the matrix line and will close the ends of the mold slot not closed by the matrix line, and the jaw 3 or both of the jaws if connected by the pinion 7, will be retracted or returned to their normal open position after a cast has been made from the matrix line, by upward swing of the lever 29 which swings the levers 22 and 24 back toward their initial position, re-= lieving the tension on the spring 20 and causing the link 13 to return toward the right in Fig. 1 or Fig. 4.

The right-hand jaw 3 is shown provided with a latch for holding it in its normal right-hand position, the latch comprising a hook-like member 30 which is fixed to the jaw 3 and a lever 31 having a hook-like end to engage the member 30, the lever 31 being pivoted at 32 on a relatively stationary bracket 33 suitably mounted on the vise cap 1, and a spring 34 acting to engage the hook on the lever 31 with that of the member 30. The lever 31 is provided with an arm 35 which is fixed thereto and extends in front of the jaw 3 and is provided with a finger 36 which lies in the path of the lower edge of the front jaw 4 of the first elevator, so that as the first elevator approaches its lowermost position to introduce the matrix line between the vise jaws, the lower edge of its forward jaw will engage and depress the arm 35 and also the lever 31 to which it is fixed, thereby unlatching the jaw 3 so that the latter may move inwardly against the end of the matrix line, the operation of this latch being similar to that shown and described in my said prior application.

According to the present invention, a single pawl common to both jaws serves to actuate one or both jaws, according to whether they are unconnected or are connected by the pinion 7, to clamp and lock the matrix line, and such pawl is preferably carried or operated by the usual justifying mechanism of the machine so that the pawl will not only be operated conveniently from a properly timed part of the machine but abnormal movement of the justifying mechanism is controlled or prevented, so that stoppage of the machine when provided, as usual, with a metal pump stop mechanism controlled by the justifying mechanism, will be prevented when there are no expansible spacebands in the matrix line to limit or arrest the motion of the justifying mechanism, as in casting from full length matrix lines containing the usual expansible spacers which are expanded by the justifying mechanism.

In the construction shown, 37 and 38 represent the usual vertically reciprocatory rods or members of the justifying mechanism, they being connected at their upper ends by a justifying bar 39 which is arranged to engage the lower ends of the usual wedge or expansible spacebands and to force them upwardly to fill out or expand the matrix line. According to the present invention, as shown in Figs. 1 to 3 inclusive, a bracket 40 is fixed to the justifying mechanism, it being preferably fixed to the upper end of the rod or member 37 and is offset forwardly therefrom, and

this bracket carries a pawl 41 which is toothed on its upper end to engage teeth 42 which are spaced longitudinally along the lower edge of the rack bar 8. The pawl 41 is movable relatively to the bracket 40 in a direction obliquely to the direction of reciprocation of the rod or member 37 or in a direction vertically and horizontally in the direction of movement of the vise jaws, the pawl having, for example, a shank 43 which fits slidably in a slot 44 in the bracket 40 and having a rib at its rear side which is slidable in a groove 7'.

45 which extends obliquely in the bracket. A pin 46 is fixed to the pawl and extends forwardly through an oblique slot 47 in the forward wall of the bracket, and a tension spring 48 connects the pi, 4G to a pin 49 which is fixed to the bracket, 3':

this spring acting to normally hold the pawl 41 in its uppermost elevated position and toward the right-hand jaw 3, the movement of the pawl into said position being limited by the end of the slot 47 in cooperation with the pin 46. understood that the rods or members 37 and 38 of the justifying mechanism are guided toward their upper ends in suitable bearings in the vise frame so that they will reciprocate vertically.

The operation of the improved quadding and j lever 29 will swing downwardly to apply j aw-clos- 3 ing tension to the spring 20, and if the matrix line is a relatively short one and requires quadding out at one end only, whether or not it contains expansible spacebands, the pinion '7 and its shaft 8 are set in their forward position out It will be ji of engagement with the racks 5 and 6, and the spring 20 will then act to close in the jaw 3 against the end or the matrix line. The upward movement of the justifying mechanism, which takes place thereafter, and, incidentally, immediately after the first elevator has been given the usual slight upward movement to aline the rear lower ears of the matrices against the mold alining groove, causes the toothed pawl 41 to move upwardly from its normally disengaged position, into engagement with the teeth 42 on the rack bar 6, toward the end of the upward movement or" the justifying mechanism, and upon continued upward movement of the justifying mechanism, the pawl 41 will exert a horizontal pull on the rack bar 6 to move the jaw 3 toward the jaw 2 to clamp the line of matrices tightly between the jaws so that first, if no expansible spacebands are present in the matrix line, a cast can be made without danger of a metal squirt and the jaw 3 will be locked in closed position against the line until the justification mechanism descends or retreats, and second, if spacebands are present in the line, the justification bar 39 will drive the wedge spacebands up wardly in the usual manner and move the 3 away from the jaw 2 until the spacebands have been driven upwardly a sufficient amount to allow engagement of the pawl 41 with the rack bar 6, whereupon the jaw 3 will be locked against further movement away from the jaw 2, and upon continued upward movement of the justification bar 39, the jaw 3 will be moved toward the jaw 2 and clamped tightly against the matrix line. The upward drive of the justifying mechanism against the wedge spacebands in the latter instance will move the jaw 3 away from the jaw 2 against the tension of the spring 20 and will thereby create a slightly wider space between the words or characters in the line but such is not usually objectionable.

If it is desired to center a matrix line with respect to the length of the mold cavity, the pinion '7 is pushed rearwardly into mesh with the rack bars 5 and 6, and the action or" the jaw-closing means will then cause both jaws 2 and 3 to move inwardly or toward one another to close in against the respective ends of the matrix line, due to the motion-transmitting connection provided between the jaws by the pinion 7, and the following action of the justifying mechanism and of the jaw clamping and looking pawl 41 will be the same as described above, although in this instance, such clamping or looking movement as is imparted to the 3 by the pawl 41 will be transmitted to the jaw 2 through the jaw connecting pinion '7, so that the jaws will move in equally and clamp against and lock the respective ends of the line. It will be understood that the matrix lines to be centered may or may not contain the usual wedge or expansible spacebands, the presenceof such spacebands being rarely required in practice since a matrix line to be centered need have only the usual blank space matrices which are always available for assembly in the line from the usual keyboard of the machine, but whether such expansible spacebands are present or not, the matrix line will be centered and tightly clamped and locked so that a cast may be made therefrom.

Casting from full or substantially full length matrix lines which do not contain any expansible spacebands may be accomplished in the same manner described above respecting the making of casts from short lines, the pawl 41 coming into engagement with the raci: bar 6 attached to the jaw 3, whether said jaw occupies its fully retracted or normal position or any position inwardly therefrom, and acting in the manner already described to clamp and lock the matrix line tightly so that a cast may be made therefrom without leakage of metal.

After the cast has been made from a short matrix line with or without expansible spacebands or a full line without such spacebands, the justifying mechanism descends or recedes from the position shown in Fig. 1 in which the jaws are locked, the first part of the descent of the justifying mechanism causing the pawl 41 to recede toward the right in that figure, by reason of its oblique movement relatively to the movement of the justifying member 37, thereby causing said pawl to release the clamping and looking pressure on the vise jaws, and the continued descent of the justifying mechanism results in carrying the pawl 41 downwardly so that it disengages from the rack bar 6, and since this pawl normally occupies such lowered disengaged position the jaw 3 or both of the jaws will then be free to be retracted or restored to their normal opened position without interference from this pawl.

Clamping and locking of full length lines containing expansible spacebands as usual, takes place in the usual manner, the spacebands being pushed upwardly by the up stroke of the justification bar 39, thus filling out the space between the vise jaws, and since the vise jaws are then held in their outermost positions against i the stops commonly employed in machines of this class, the up stroke of the justifying mechanism will be arrested by the spacebands in the usual way before the pawl 41 comes into engagement with the rack bar 6.

When full length matrix lines, either with or without expansible spacebands are presented between the vise jaws, the pinion is disengaged from the rack bars 5 and 6, the righ -hand vise jaw 3 being then looked against the line by the usual stop commonly employed in the machine for such jaw if spacebands are present in the line or by the action of the pawl 41 if no spacebands are present in the line, and the left-hand jaw 2 being clamped and locked against the line clamp and loci: the left-hand end of the line when -a.;'

the latter is quadded out or indented only at its right-hand end.

Since the clamping and locking pawl 41, after it comes into engagement with the rack bar 6,

will act to clamp and lock the jaw 3 against the end of the matrix line when the line is short and is to be indented at one end, and to clamp and lock the jaws 2 and 3 against the respective end of the matrix line when the line is short and is to be centered or indented at both ends or is of full length, the jaw or jaws being thus forced inwardly from the position or positions into which it or they have been brought by the jaw-closing means to close theline, or from their normal retracted positions, according to whether the l T matrix line is of any length less than full length or is of the full length or measure to which the machine is set, tight clamping and locking of each line irrespective of its length is accomplished automatically, even though the line may not contain any wedge or expansible spacebands, so that casting of the type bars or slugs therefrom may be accomplished without any danger of a metal squirt.

For certain classes of printing, wide spacing between the words in a short line may be objectionable, and the modified form of the invention shown in Figs. 4 and 5 is provided to overcome such objection. In the form of the invention shown in these figures, it is to be understood that the jaw-closing means and the pinion and racks for connecting the jaws will be constructed and operated in the same manner as shown and described in connection with Figs. 1 to 3 inclusive. In Figs. 4 and 5 however, a bracket 40 is provided for the pawl 41 which is similar to the bracket 40 previously described, but the bracket 40 is provided with a post at one side thereof and depending therefrom, it being secured thereto by screws 51 and a support 52 is fixed on the vice frame 1 and serves for mounting and guiding the post 50 for vertical movement. A pin 53 in the post 50 operates vertically in a slot 54 in the support 52 to prevent turning of the post 50 therein. A plunger 55 extends transversely through and is reciprocable horizontally in the bracket 40*, the outer end of this plunger 55 being connected by a link 56 to a lever 57 pivoted on a screw 58, the latter being secured in the edge of the usual right-hand guide for the first elevator i, this guide being of the same form as the left-hand guide 59 shown in Fig. 4. The plunger 55 is of sufiicient length to extend inwardly into the path of the upward stroke of the bracket 39 to which the justification bar 39 is secured whenever the lever 57 occupies the position shown in Fig. 5.

According to this construction, when a short matrix line either containing spacebands or without spacebands, is presented between the jaws for casting, the jaw 3 will be moved toward the jaw 2 in the manner hereinbefore described in connection with Figs. 1 to 3 inclusive, to quad out the incomplete line, and the justification bar 39 will move upwardly in the usual manner, whereupon the bracket 39 to which the bar 39 is secured will contact with the rear end of the plunger 55 and move the bracket 40 upwardly so that the pawl 41 carried thereby will come into engagement with the toothed lower edge of the rack bar 6 connected to the jaw 3 and will then move toward the jaw 2 to clamp and lock the jaw 3 tightly against the line. If the line contains spacebands, such spacebands will be driven upwardly and will expand the line against the jaw 3, which is free to be moved away from the jaw 2 to allow such expansion until locked by the pawl 41. It will be seen that this arrangement of the parts, wherein the pawl 41 comes into engagement with the rack bar 6 before the spacebands have been driven upwardly to their full extent, as in the previously described construction, will result in a closer and narrower spacing between the words in the line than would be possible with the pawl mounted on the justification bar 39, as in the previously described construction.

In using this arrangement, whenever a cast is to be made from a short line to be quadded, it

, is necessary to position the lever 57 as shown in Fig. 5. While casting normally from full length lines containing spacebands, it is necessary to swing the lever 57 about its pivot 58 in order to retract the plunger 55 out of the path of the justification mechanism, a conveniently accessible handle 60 being provided on the upper end of the lever 57 for this purpose. While casting normally from full length lines containing spacebands, it is also necessary that the jaw 3 be locked in its normal position so that when the first elevator 4 moves downwardly to present the matrix line between the jaws 2 and 3, the jaw 3, which is released by the downward movement of the first elevator, which disengages the members 30 and 31, as described in connection with Figs. 1 to 3 inclusive, will not move toward the jaw 2 upon such disengagement, under the action of the jaw-closing means. For this purpose, a pin 61 is pivotally secured to the lever 57 above its pivot screw 58, this pin being movable rearwardly through an aperture provided in the vice cap and extending therethrough and into a recess 62 in the usual jaw block 3 to which the jaw 3 is secured, whenever the lever 57 is positioned to retract the plunger 55, or is in the reverse position to that shown in Fig. 5.

A pawl 63 is provided at the upper end of the lever 57 to control the position of said lever in accordance with the matter being composed in the machine, that is, if a number of short lines are to be cast from in succession, in which the jaw 3 must move toward the jaw 2. to quad out the unfilled portion of the line in each case, it is desirable that the lever 57 be held in the position shown in Fig. 5 sothat the jaw-locking pin 61 will be disengaged from the jaw 3. On the other hand, while full lines are being composed and a short line occurs infrequently, as at the end of a paragraph, it is desirable that the lever 57 be held in such a position that the jaw-locking pin 61 will engage and lock the jaw 3, except when an occasional short line occurs, and the arrangement of the parts, as shown in Figs. 4 and 5, is such that in the latter instance the lever 57 may be swung to the position shown in Fig. 5 to eiiect disengagement of the pin 61 from the jaw 3.

Means is preferably provided for returning the lever 57 to jaw-locking position after it has been moved to the position shown in Fig. 5 for an occasional short line, through the operation of the usual first elevator. For this purpose, the first elevator is provided with a pin 64 which projects laterally therefrom and travels vertically in the path of the pawl 63 when the latter occupies the full line position shown in Fig. 5. When the matrix line is lifted from between the jaws after casting, the pin 64 will engage the pawl 63 and will swing the latter about its pivot on the hub of the operating handle 60 for the lever 57, and will thereby swing the lever 57 about its pivot 58 so that the pin 61 will enter the recess 62 in the jaw block 3 This same movement of the lever 57 will retract the plunger 55 from the path of the justifying mechanism so that the machine will operate in the normal manner for the next full line that is sent in for a cast, the locking of the jaw 3 by the pin 61 preventing movement of this jaw inwardly from its normal position under the action of the jaw-closing means and thereby insuring filling out of the line to its full measure by the expansion of the usual spacebands. If a number of short lines are to be cast successively, the pawl 63 may be swung to the dotted line position shown in Fig. 5 and the lever 57 moved into the position shown in this figure so that the jaw 3 will then be unlocked by retraction of the pin 61 and free to move toward the jaw 2 under the action of the jaw-closing means for each successive line and the plunger will be in position to overlie at its rear end and thereby arrest the upward stroke of the justification bar 39 and cause engagement of the clamping and locking pawl 41 with the rack 6 for each new line that is presented. A spring is provided. to hold the pawl 63 in either the full or dotted line position shown in Fig. 5, a pin 66 being secured in the lever 5'? to serve as a stop for the pawl 63 when the latter is positioned either in the full line or operative position or the inactive or dotted line position shown in Fig. 5. It will be understood that after each cast has been made and the justification mechanism retreats downwardly after engaging the plunger 55 and actuating the pawl 41, the pawl bracket 40 and the pawl 41 fall back to normal position as shown in Fig. 4 by gravity.

With the above noted exceptions, the operation of the form of the invention shown in Figs. 4 and 5 is similar to that described in connection with Figs. l to 3 inclusive, it possessing the additional advantages of avoiding undue spacing of the words in short matrix lines containing spacebands when quadded out and insuring casts of full measure or length from full matrix lines containing spacebands, the closing and clamping of short or full length matrix lines not containing spacebands and the qua-doling and centering of short lines being accomplished in the same manner described in connection with Figs. 1 to 3 inclusive.

By mounting the clamping and locking" pawl on or actuating it by the justifying mechanism of the machine so that it may come into action to clamp and lock the vise jaws while the fying mechanism is making its spaceband expanding or justifying stroke, the matrix line will be clamped and locked tightly, whether or not it contains expansible spacebands and irrespective of its length, and the justifying stroke of the justifying mechanism will be arrested wi hin its normal limit by said pawl the movement or which is limited by the locking of the matrix line.

The provision of a single clamping and locking pawl to act either on one of the vise jaws or upon both of the vise jaws when the latter are connected by the motion-tra' mitting pinion or its equivalent, greatly simpli' es the construction and reduces the number of parts required, and its mounting on or actuation by the justifying means insures the correct timing of its operation. Moreover, this pawl is so arranged that it will come into action, in each instance, prior to movement of the ying mechanism amount sufficient to operate the usual pump stop and prevent a cast, so that the justifying mechanism will always be blocked against operating to its full height when a matrix line is presented between the vise jaws and hence a cast can be made a line of any length with or without expansible spacebands.
